You’ve pretty much nailed it on the head. They are going to be almost identical in performance. They are both for the most part aluminum cookware with a stainless cooking surface. The major advantage to the Stainless is that it will be almost maintenance free. The MC2 will oxidize in the dishwashing faster than if hand washed but will eventually need to be cleaned with some kind of cookware cleaner like Kuhn Rikon Swiss Cleaner to maintain the original polished look.
